The resent invention relates to closure means or garments, footwear and the like, having sliding locks, said closure means being arranged in series or rows at the edges or borders of the garments. Between the rows of the closure members sliding members for opening and locking the closure means are provided, the heads of the closure members being equipped on the one side with raised tongues, lugs or the like, while corresponding recesses or cavities are provided in complementary members which engage the other closure members in the closed or locked position of the closure.

Similar closure means have been heretofore employed, the difierences residing in the form and arrangement of the closure heads with their mutual engaging parts which generally have the form of plates or shells and which preferably are produced by stamping. Stamping of the closure heads, however, is only possible when the thickness of the metal is small and it is difficult to produce this particular type. This difliculty becomes essentially greater when such closure means are provided with an arrangement of ribs, grooves or the like, for special purposes of application, in order to prevent a relative turning or angular movement of the locking members.

Now it has been found that the mutual engagement of the locking heads can be produced in a simple manner and independent of a predetermined thickness of material, if tongues or lugs are stamped out from a plate and bent over or downwardly in such a manner that the point of the tongue projects on the under side of the plate as a raised lug, while the cavity or recess which is formed on the upper surface by bending over the tongue serves" for the engagement of the lug. The engaging parts are made or produced in a very simple manner, as only an ordinary stamping operation is necessary. By selecting the proper shape of the stamped-out part and a suitable bending angle for the tongue, the engaging parts may be made slightly or deeply raised and flexible or rigid without needing special devices for this purpose.

In the type of sliding locks now used the individual rows of locking means generally have only one engagement or grip. For giving to these closures greater strength and better hold and for removing the movability to all sides, it has been suggested to shape the engaging parts irregularly or cam-like, instead of round, or to arrange in the engaging cavities or recesses, ribs, grooves, or the like, which engage each other in the two cooperating parts and make a turning or angular movement or shifting impossible, which is very important for an easy manipulation of the slide.

Accordingly the invention consists in providing closure heads for the individual closing members having two juxtaposed connecting points which may have any desired form, for instance, the form of tongues. By this doubling an angular shifting of the members is avoided, the same being true when a smooth spherical form of shell or plate is employed. In the transversal direction of the members a great elasticity and flexibility is provided without producing the danger of a snapping-out of the lock, as the individual 76 -members will always stay in engagement on the one side-when the other side is more or less raised by an inward bending of the closure means.

For safely guiding the closure members in 80 opening and closing, a rigid engagementof the slide into the members is provided, the arrangement being similar to a feather and' groove.

The closure means are generally placed or fixed in series on a ribbon made of cotton. As cotton is influenced by weather conditions, it is possible for the series or rows of the closure means to become staggered in their relation by a Warping or shrinking of the ribbons. To prevent this, according to the present invention, the cotton ribbon is impregnated, coated or otherwise treated prior to or after the fixing of the closure means in order to make it waterproof.

The slide which serves for opening-and locking the closure means consists essentially in two shields or plates which overlap the rows or closure means and which are connected with each other by a rivet.

Fig. 8 shows two individual locking members in longitudinal section on large scale, showing another embodiment of the invention.

The individual closure or locking members 1 are mounted in the usual manner on the edges of cotton strips or ribbons which, in their turn, are fixed on textile webs or strips, which are secured together. The cotton strips are, according to this invention, impregnated or otherwise treated so that they are'weatherproof and protected against warping.

The locking members 1 are opened and locked by a slide 3; each of said locking members consists of a smooth plate, whose effective locking head is so formed that a tongue is stamped out from the head surface of the plate and bent downwardly about a fixed edge so that the point of the tongue protrudes from the plate and forms a projecting lug, while 40 by bending the tongue a cavity 4 is formed on the surface of the plate, into which, when the lock is closed, the lug or tongue of the next following member engages.

Figs. 3 and 8 show various embodiments or forms of the tongue. According to Figs. 3 and 4 the tongues 5 are rectangularly stamped towards the front. According to Figs. 5 and 6 the tongues 5 have triangular form and are also stamped out towards the front. In the case of Fig. 7 the tongue 5 has an arcuatefree edge,whereby the closure or lock is made more flexible, while in the previous forms the individual members are very rigidly connected with each other, so so that a lateral bending of same relative to each other is prevented as the lugs engage on all sides with straight edges into the stamped cavities, which also have straight edges.

The formation of the lugs by the bent point of the tongue has the further advantage that the center line or alignment of the points of the lugs which is indicated in Figs. 3 and 5 by the dash dotted line II is shifted ahead on the underside of the plate relative to the center line II-II of the stamped opening in the direction of the bend,so that also the in- According to the bending angle of the tongues the distance of the members from each other can be'selected to be larger or smaller without interrupting or impeding the connection.

What I claim is:

1. A sliding lock for garments and the like comprising uniform locking members fixed in series on the borders of textile, leather or other strips, and a sliding member arranged to slide between the rows of the locking members for opening and closing the lock, said locking members being provided at their locking heads on the one side with recesses and on the other side with protruding members, said lockin members consisting of flat plates, in which the protruding parts and the recesses are formed by tongues stamped-out of the head plates and downwardly bent in such a manner as to be entirely within the front and side margins of the locking members.

2. A sliding lock for garments and the like comprising uniform locking members fixed on the borders of textile, leather or other strips in series and a sliding member arranged between the rows of the locking members for opening and closing the lock, said locking members having locking heads which are provided on the one side with recesses and on the other side with protruding parts, said locking members consisting of flat plates, in which the protruding parts and their recesses are formed by stamped-out tongues which are downwardly bent in such a manner as to be entirely within the front and side margins of the locking members, the lower edge of said tongues being advanced forwardly relative to the median lines of the stamped openings.

In testimony whereof I aflix my signature MARTIN WINTERHALTER.
